Merge branches 'clk-spdx', 'clk-qcom-dfs', 'clk-smp2s11-include', 'clk-qcom-8996-missing' and 'clk-qcom-qspi' into clk-next 

- Tag various drivers with SPDX license tags
  - Support dynamic frequency switching (DFS) on qcom SDM845 GCC
  - Only use s2mps11 dt-binding defines instead of redefining them in the driver
  - Add some more missing clks to qcom MSM8996 GCC
  - Quad SPI clks on qcom SDM845

* clk-spdx:
  clk: mvebu: use SPDX-License-Identifier
  clk: renesas: Convert to SPDX identifiers
  clk: renesas: use SPDX identifier for Renesas drivers
  clk: s2mps11,s3c64xx: Add SPDX license identifiers
  clk: max77686: Add SPDX license identifiers

* clk-qcom-dfs:
  clk: qcom: Allocate space for NULL terimation in DFS table
  clk: qcom: gcc: Register QUPv3 RCGs for DFS on SDM845
  clk: qcom: Add support for RCG to register for DFS

* clk-smp2s11-include:
  clk: s2mps11: Use existing defines from bindings for clock IDs

* clk-qcom-8996-missing:
  clk: qcom: Add some missing gcc clks for msm8996

* clk-qcom-qspi:
  clk: qcom: Add qspi (Quad SPI) clocks for sdm845
  clk: qcom: Add qspi (Quad SPI) clock defines for sdm845 to header
